What Are Stainless Steel 310 Butt Weld Fittings?
Stainless Steel 310 Butt weld Fittings are specialized pipe connectors designed for severe-service applications involving high temperatures. They are joined to pipes using a butt-welding technique, where the beveled ends of the fitting and pipe are welded together to form a continuous, leak-proof, and structurally robust joint.
The exceptional capabilities of Grade 310 (UNS S31000) stem from its high-alloy austenitic composition, which typically includes 25% chromium and 20% nickel. This rich chemical makeup gives 310 Stainless Steel Pipe Fittings their signature properties:
- Outstanding Oxidation Resistance: The high chromium content forms a stable, protective chromium oxide layer on the surface, making the fittings highly resistant to oxidation and scaling at continuous service temperatures up to 1040°C (1900°F) and intermittent temperatures up to 1150°C (2100°F).
- Excellent High-Temperature Strength: The high nickel content ensures the material retains good strength and a stable austenitic structure even at extreme temperatures, resisting deformation and maintaining integrity.
- Good Resistance to Hot Corrosion: This grade performs well in carburizing and moderately oxidizing, nitriding, cementing, and thermal cycling applications, though it is not recommended for environments with high thermal shock or aqueous corrosion.
These characteristics make SS 310 Fittings for Heat Exchangers, furnaces, and kilns the industry standard. As a dedicated manufacturer, Amardeep Steel ensures every SS 310 Butt Weld Pipe Fitting provides the long-term reliability required for critical high-temperature operations.

Heat Treatment & Tolerances of Stainless Steel 310 Butt weld Fittings
Our manufacturing process incorporates critical heat treatment and dimensional controls to ensure every fitting meets the highest standards of quality.
Heat Treatment Requirements
All ASTM A403 WP310 Fittings are supplied in the solution-annealed condition. This heat treatment involves heating the material to a temperature range of 1040-1150°C (1900-2100°F) and then quenching it rapidly in water or air. This process dissolves carbides, homogenizes the austenitic structure, and restores maximum corrosion resistance and ductility.
Dimensional Tolerances
We manufacture ASME B16.9 310 Butt Weld Fittings to the exact dimensional tolerances specified in the standard. This commitment to precision ensures:
- Accurate center-to-face and end-to-end dimensions for predictable layouts.
- Correct angularity of elbows and tees for perfect alignment.
- Consistent wall thickness for uniform pressure handling.
- Properly formed end bevels for efficient and high-quality welding.
This precision minimizes field adjustments and ensures a smooth installation process.

Frequently Asked Questions (FAQ's)
1. What is the main difference between Stainless Steel 310 and 310S fittings?
The primary difference is the carbon content. Grade 310 has a higher carbon content (up to 0.25%), which provides better high-temperature strength and creep resistance. Grade 310S has a lower carbon content (≤0.08%), which makes it less prone to embrittlement and sensitization in service and improves its weldability.
2. What is the maximum temperature Stainless Steel 310 Butt weld Fittings can withstand?
Grade 310 offers excellent oxidation resistance in continuous service up to 1040°C (1900°F) and in intermittent service up to 1150°C (2100°F).
3. Are 310 Stainless Steel Pipe Fittings magnetic?
No. Like most austenitic stainless steels, Grade 310 is non-magnetic in the annealed condition. It may become slightly magnetic after extensive cold working, but this is uncommon for fittings.
4. Can I use SS 310 fittings for wet or aqueous corrosion environments?
While SS 310 has good general corrosion resistance, it is not designed for wet corrosive environments, especially those containing chlorides, where grades like 316L or Duplex steels would perform better. Its primary strength is in high-temperature, non-aqueous applications.
5. What information is needed for an accurate price quote?
To provide you with the most accurate price and delivery schedule, please include the fitting type (e.g., 90° LR Elbow, Eccentric Reducer), nominal pipe size, wall thickness or schedule (e.g., Sch 40s), required quantity, and any special certification or testing requirements.
